WaveNet Site Survey Tool User's Manual
Document: UM-1000 Revision Level B
The Simulate Tx Mode allows the SST to simulate a WaveCast Monitor (WCM) and transmit
data to WaveLink Receivers and WaveNet Relayers. The Radio Setup menu will only allow
operation as a Client in this mode. To avoid accidental transmission to an active channel, the
default channel for this mode is diagnostic channel 33. Channel 33 does not affect alarms at
WLR’s or WNR’s but is received and acknowledged (ACK) by their radios. This ACK is used to
capture RSSI from a server’s returned packet. Items available in this mode are:
REMOTE ID = Channel number setting of 1-33. Channel 33 is the default channel since it
does not affect any alarms as described above.
Warning: SST’s simulating WaveCast monitors in this Tx mode transmit packets
with all alarms cleared and Value Register set to 800 counts (ZERO READING). If
sent to a channel on the WLR or WNR that is in alarm ALL ALARMS WILL CLEAR
AND READING RETURN TO ZERO.
TX Interval = Value controlling if packets are transmitted manually (SINGLE) or
automatically every 6Sec, 1Min or 5Min. When set to SINGLE, packets are only sent
when the Send Packet menu is selected and the SEND key is pressed. Other settings will
automatically send packets on the interval displayed.
Send Packet = Sends each packet on demand by pressing the SEND key if the TX Interval
is SINGLE. If TX Interval is 6Sec, 1Min or 5Min the Send Packet field is a count-down
timer displayed in seconds and the packet is sent when the timer reaches zero and the
timer resets to the TX Interval. Once sent, the Packet Count advances and upon a return
of the acknowledgement, the ACK Received will advance and the RSSI will be displayed
for that reception. This can be useful to determine the missed packet ratio. Also, upon
the ACK, the dBm is captured for that packet and displayed as Last RSSI.
Trend Server RSSI = A unique test mode where the SST transmits a packet to the
network Server’s channel 33 approximately twice per second, and only the Server
returns an ACK. When the ACK is received, the SST increments the ACKS RECEIVED
counter, reads and averages the RSSI and draws an RSSI trendas a trend. A percentage
value for ACKs RECEIVED is displayed across the top and should be > 95%. The most
recent RSSI value appears at the bottom of the screen along with the RESET and DONE
keys. Press RESET to start over on the fly and DONE to end the test. Pressing DONE
brings up the results of the test including % of ACK’s received, packets sent and received
counters and HIGH, LOW and AVERAGE RSSI values.
Packet Count = Running count of the number of packets sent by the Tx Interval settings.
This may be reset to zero by selecting this item and pressing the RESET (F3) key.
